Custom Form Field With Multiple Inputs

  1. Hi,

    I am trying to create a form that gets the latitude and longitude from Google maps and saves it to a custom table in WordPress.

    Currently i have created a the required fields and everything populates as expected.

    I have then added a custom field type to gravity forms. This renders fine on the client side however doesn't appear to be working on the server side as it is not sending the values through to gravity forms... i would like the function to display as the name field displays in entries.

    I am hoping you maybe able to let me know where i am going wrong

    // Add a custom field button to the advanced to the field editor
    add_filter( 'gform_add_field_buttons', 'add_loc_field' );
    function add_loc_field( $field_groups ) {
        foreach( $field_groups as &$group ){
            //if( $group["name"] == "advanced_fields" ){ // to add to the Advanced Fields
            //if( $group["name"] == "standard_fields" ){ // to add to the Standard Fields
            if( $group["name"] == "post_fields" ){ // to add to the Standard Fields
                $group["fields"][] = array(

  2. Explain what you mean that it works on the client side, not the server side. What does that mean? Is the display of the submitted data missing from the entry view?

    Thank you.

  3. HI Chris,

    Thanks for your reply,
    yeah that is exactly what is happening.

    It displays fine in the browser, but doesn't seem to pass the information to the entries layout in the admin.

  4. I, too, would be interested in the steps necessary to correctly create and integrate my own *custom* Advanced Fields into Gravity Forms.

    The *custom* Advanced Field would contain the following elements: Firstname, Lastname, 2 input fields, birthdate, days-of-the-week single-select drop-down, and time. Then would like to be able to create conditional checkbox(s) that would display/hide instances of this object.

    Any feedback or tutorials would be great. So far, the only example I can find is this posting and from WPSmith, http://wpsmith.net/2011/plugins/how-to-create-a-custom-form-field-in-gravity-forms-with-a-terms-of-service-form-field-example/.

    Best...

  5. Unfortunately, this post was closed, http://www.gravityhelp.com/forums/topic/extending-gravityform, and it no longer open to replies. The above example from WPSmith is a good start, but it does not explain how to create an Advanced Field type with more than one element as I described in my previous comment. Any further examples/insight would be more than helpful.

    Additionally, as a feature request, the ability to create/edit an XML document that contained definitions of your Advanced Field types would be hightly beneficial because then people could create/edit their own Advanced Field types without having to become highly familiar with PHP and JQuery and the nuances of the internals of Gravity Forms. This would allow users to apply limitless combinations of form types to Gravity Forms and extend it's usefulness.

    Best...

  6. Did you ever make progress on this?

  7. Friend, there's an error at line 11, instead "onclick" => "StartAddField('add_loc'), put onclick" => "StartAddField('addloc'); without the underline character at "addloc"... Obviously, all "add_loc" reference (type) will not work, so I suggest you to substitute every "add_loc" therm to "addloc".
